This USB 3.0 dual Type-A male to 20-pin motherboard header Y cable allows two external USB-A ports to connect directly to a single internal USB 3.0 (20-pin) motherboard header. It is commonly used for PC case modifications, test benches, internal USB routing, and development setups where external USB devices need to interface with the internal motherboard header.
The 20-pin header provides two USB 3.0 channels, matching the dual USB-A male connectors. This cable does not increase USB speed or create additional bandwidth; it simply routes the two standard USB 3.0 lanes from the motherboard header to external USB-A connectors.
